The idea that, at this point in every single reader's life they need "substance" along with ideas, is just a bit much. You, at this point in your life, would want/need more substance but you are just one person. There is a lot of value for other people in reading bullet point lists of these types of things. For example, if these are all things I've known and learned in my 42 years on the earth, a bullet point list serves as a nice, general reminder on a lot of levels. The "I've forgotten more about productivity hacking than most 20 year olds have learned" adage is true here for 40yos. Maybe you are at the point where some of these are recent topics for you - things you've recently learned in much longer format. So you reject it as "Everyone knows this - silly". We all have biases - we just have to view things from others' perspectives sometimes to avoid those biases coloring our outlook.
